notes

von Tschirnhaus (1999a) considers Ph. salviae (Hering, 1924) synonymous with rydeni, in which case salviae would be the valid name. This does seem untenable: the hostplants (Salvia and Ballota, respectively) are widely separated from the one of rydeni and the mines are completely different. von Tschirnhaus’ opinion is not shared by the Fauna Europaea (2008) either.
